Making fuel from sunlight

Researchers have developed a reactor that can rapidly produce fuel from sunlight, using carbon dioxide and water, plus a compound called ceric oxide. “High-Flux Solar-Driven Thermochemical Dissociation of CO2 and H2O Using Nonstoichiometric Ceria,” by W.C. Chueh et al. Science, January 2011 Because solar energy is available in large excess relative to current rates of …
